Before installing Xupport 3, please check the following:

• Make sure installing the proper application version. The download includes an installer for Panther (Mac OS X 10.3.x), and one for Tiger (Mac OS X 10.4.x)

• I recommend to use the "Uninstaller" before installing Xupport 3. The uninstaller removes all beta and previous versions of Xupport 3, archives Xupport 2, and removes any other component installed by Xupport.
